| Cable Tube Sealing KKA-100 |
The cable tube sealing guarantees a gas- and liquid-tight sealing of cable protection tubes. The KKA is to be inserted at the end of cable protection tubes, so that no dangerous gases invade the service-building and lead to deflagration.

General Requirements:
|
|
Cables or thin pipes have to be sealed between hazardous zones and workshops. The sealing has to be gastight.
Usually cables are laid in cable protection tubes, which are located either under- or overground. The KKA is inserted at the ends of the protection tubes to avoid the penetration of mineral oil and gases into the tubes.

The sealing should not be crafted on site to guarantee the safety of the industrial premises, because the making with hemp, putty and grout is complicated and error-prone. It is better to use a product that is ready to use and therefore ensures an optimum of impermeability.
The reasons for the development of the KKA were serious accidents due to a leaky sealing. Gases invaded the service-building and resulted in a deflagration.

Description:
|
|
The KKA consists of a flexible and mineral oil resistant rubber bellow between two cover plates. The cover plates have several apertures for high-strength cable glands. Cables or thin pipes are led trough the cable glands and are sealed with a rubber gasket.
One hexagon socket holds together the cover plates. The clockwise rotation of the hexagon socket squeezes the plates together and the rubber bellow is compressed. Finally the cable tube sealing has a tight fit in the protection tube.
The effectiveness of the KKA is tested and proved by the TÜV. The certificate is available as PDF-Document.

Applications:
|
|
The KKA cable tube sealing can be used with tank installations, airbrush facilities and in the chemical industry.
Cable protection tubes with an inner diameter of approximately 97-110 mm can be sealed. The common diameter of cable tubes is 100 mm. The ends of the tubes may consist of the following materials:
- Corrosion resistant steel
- Rigid PVC or PE-HD plastic
 See datasheet for detailed information
Four cables or thin pipes with an outer diameter of 9-20 mm or several thin cables (6-8 mm) can be led trough the cover plate. Each of the high-strength cable gland inserts can take one thick or three thin cables.

Unused apertures are sealed with a universal blind plug. Therefore, the alteration or re-fitting of cables can be done with a minimum of efforts and costs.
